Rex, just an FYI the older original serial ports were also 25pin D-SUB connectors on the rear of the PC, the main physical difference was the PP had holes(female) and the serial had pins(male). Chuck

It may or may not be pink in color, but it will be a 25-pin Female connector on the PC(it will have holes instead of pins) If you find a PC with a Male 25-pin port, that IS a serial connector, and

Thanks Rex, I think I got confused because of people interchanging the terms via a google search when looking for the proper cable. I actually have the original 25 pin cable, now I just need an old

The 25 pin port is the parallel port, the one you want. The serial port is a much smaller port/connector. With a serial port, all the data goes over one pin/wire in serial fashion. With a parallel,

Ok, so it won't work it seems. I will find an old desktop. Just to be perfectly clear, (sorry, I'm not a computer guy) I want a computer with the "hot pink" 25 pin port at the back? I thought that was

Matt, you are confusing a serial port with a parallel port. mach3 will not work on a serial port or a vga port. Chuck

Hi Matt, In no way can I be called an expert in this but have been down your road earlier myself. After buying and throwing and buying and throwing; I have come to firmly believe that the only problem

Thanks for clearing that up. I knew it was to good to be true. Will a 25 pin to the smaller 9 pin serial work? I have another laptop with that. I think it's a VGA cable port or something. Will that

Thank you very much for the info! I can't wait to see if these lathes work. I will have to find a computer with a serial printer port. Thanks again. Matt.

Sam: turned out to be the anti backlash nut was moving in the holder Its rare.. but sometimes the error tells you where it is.. I could easily picture that nut moving up and down.. lol Thanks, Art

What ls the length of tool 1 in the tool table, and what is the length of the other tools that work?

Thanks to everyone for your suggestions. Art was on the money as it turned out to be the anti backlash nut was moving in the holder. Once I locked it down all is well and I still have lets see 1,2,3

Conflicting information about laptops is because some work better than others. The ones that don't, have eco settings that will kick in a screw things up. If you've got a laptop with a printer port

I have a funny problem with mach3 In my tool table I did not define specific tools and tool diameters – hope this is not a problem (but also tried the same code with the tools diameter defined in

Hey Art I am not saying it is your PC, but I had a similar problem. (LOL still having problems). I used an old PC I had (about 200 model) with windows XP on and the machine was just not stable.

mmmm try to reset z after the 2nd sheet I had a problem that the z axis lost steps on the change of direction . It took a while for it to add up ! so I wrote a program with lots of peck drilling and

You cannot use a 25 pin to usb. USB cannot be used at all. It needs to plugin into an actual 25 pin printer port. Nothing short of that will do, either a plugin pci card with a printer port on it, or

Matt, I can answer the first 2 questions. Yes Mach3 will send outputs in demo mode the only limitation of demo mode is the 500 lines of gcode. Mach3 will run on laptops the main limitation is if

Mach3 will NOT work with a USB to parallel converter cable. It needs a real parallel port, or a 3rd party motion controller like a UC100 or Smoothstepper. If you can find an older PC with a parallel

Hello there! This is my first post regarding Mach 3 and its capabilities, so please bear with me. I am a high school Metal Shop teacher trying to get some CNC going for the class. I have a few EMCO
